We investigated EEG correlates of social attention, face, and non-face perception by applying a continuous performance test (CPT) with two different sets of stimuli (letters and faces). The CPT required participants to respond to a specific target stimulus (e.g., “X”) only when it followed a specific preceding stimulus (e.g., “O”). Event-related potential (ERP) components, including P100, N170, P200, N250, P300, and continuous negative variation (CNV), were analyzed in 19 young adults with ASD and 19 typically developed (TD) individuals that were matched for intelligence, age, and gender. TD participants had higher accuracies only for the target condition and regardless of stimulus type. No ERP differences between the two groups were found for the CPT with letter stimuli. By contrast, autistic individuals exhibited lower amplitudes of P300 and CNV during face CPT. Results suggest diminished allocation of attentional resources and response preparation towards socially relevant face stimuli.

Autistic Traits are Linked to Individual Differences in Familiar Voice Identification / Verena G. SKUK in Journal of Autism and Developmental Disorders, 49-7 (July 2019)

SKUK, Auteur ; Romina PALERMO, Auteur ; Laura BROEMER, Auteur ; Stefan R. SCHWEINBERGER, Auteur Article en page(s) : p.2747-2767 Langues : Anglais (eng) Mots-clés : Autistic traits  Gender differences  Individual differences  Own-gender-bias.  Recognition  Voice Index. décimale : PER Périodiques Résumé : Autistic traits vary across the general population, and are linked with face recognition ability. Here we investigated potential links between autistic traits and voice recognition ability for personally familiar voices in a group of 30 listeners (15 female, 16-19 years) from the same local school. Autistic traits (particularly those related to communication and social interaction) were negatively correlated with voice recognition, such that more autistic traits were associated with fewer familiar voices identified and less ability to discriminate familiar from unfamiliar voices. In addition, our results suggest enhanced accessibility of personal semantic information in women compared to men. Overall, this study establishes a detailed pattern of relationships between voice identification performance and autistic traits in the general population.

Disentangling the perceptual underpinnings of autism: Evidence from a face aftereffects experiment / Julius HENNIG ; Arne DOOSE ; Clara Marie BREIER ; Alexander SOUTSCHEK ; Nicole BEYER ; Stefan SCHWEINBERGER ; Inge KAMP-BECKER ; Luise POUSTKA ; Katja ALBERTOWSKI ; Veit ROESSNER ; Stefan EHRLICH in Autism Research, 18-2 (February 2025)

However, the exact underlying mechanisms, such as sensory dominance possibly caused by imprecise priors and/or increased sensory precision, remain elusive. The ?Bayesian brain framework offers refined methods to investigate these mechanisms. This study utilized both model-free (frequentist statistics) and model-based (hierarchical Drift Diffusion Modeling) analytical approaches to compare gender face aftereffects in male adolescents with autism (n 29) to neurotypical controls (n 39) using a behavioral choice experiment. Contrary to our initial hypotheses, our analyses did not find support for imprecise priors or increased sensory precision within the autistic group. Instead, we observed generally decreased drift rates towards male but not female stimuli in the autistic group. Thus, our findings suggest a lack of own-gender bias in face processing among the autistic participants. These findings align with more recent behavioral and neurophysiological research observing intact priors in individuals with autism, suggesting that other mechanisms may better explain the perceptual challenges in autism. Our study contributes to the ongoing discourse on perceptual processing in autism, emphasizing the necessity for more nuanced analytical approaches in order to unravel the complexity of this condition.
